Run the install (even though it fails) but leave it open on the screen at the end that says "Installation Did Not Succeed" (This is very important!)

Now you need to track down the temp files for the installer it should be in a folder {drive}:/Temp/ext27692 (probably this goes onto whatever drive has the most free space)

Make a copy of this entire folder because finishing the installer will delete it.

Now that you have all the install files you just need to run the installers for the different components (to double check what they were you can open the log from the installer and see which msi's it ran)

So install AspNetWebPagesVS2010Tools.msi then AspNetMVC3VS2010Tools.msi
